Attending to cross-border sociocultural competence in bilingual programs in the Polish-Czech border region: An exploratory study.

The aim of this research was to explore whether and how various components of cross-border sociocultural competence were attended to in bilingual schools serving Polish minorities in the Zaolzie border region. Zaolzie is on the Czech side of the Polish-Czech border region, where the Polish minority play an important role in cross-border relations. Based on a review of the extant literature on the development of sociocultural competence among students enrolled in bilingual programs, researchers developed a 19-item survey capturing three distinct components of cross-border sociocultural competence: cognitive, social, and political. The survey was sent to teachers in the 14 Zaolzie region schools, with 123 teachers (44%) participating and asked participants to indicate the extent to which different facets of cross-border sociocultural competence were part of their school's instructional program. Most participants were female-identifying and had over 10 years of teaching experience, and most were born on the Czech side of the border but identified as Polish nationals. Results from an exploratory factor analysis (EFA) revealed two unique factors representing different components of sociocultural competence included in bilingual programs in the Zaolzie region: (1) the development of students' intrapersonal skills, motivation, and cross-linguistic understanding, and (2) the development of students' capacity to engage interpersonally with and to understand others in the region. These findings suggest that schools in the Zaolzie region attend to cross-border sociocultural competence through both an intra- and interpersonal lens, emphasizing individual students' linguistic and cultural development as well as their ability to interact in their highly politicized cross-border context. Educators in the region can thus consider assessing students' progress in these two areas over time as measures of program effectiveness. Given that the researchers found that cognitive, social, and political aspects of sociocultural competence were integrated across intra- and interpersonal dimensions, more research is needed to understand if this integration is unique to the teaching of cross-border sociocultural competence in the Zaolzie region or is taught similarly in other contexts.

Understanding pathways from narcissistic grandiosity to psychotic-like experiences: Insights from the network analysis.

It has been shown that narcissistic grandiosity and psychotic-like experiences (PLEs) may share the common psychological mechanisms, including impairments of metacognition, social cognition, cognitive biases, emotion regulation through fantasizing and dissociation. However, it remains unknown as to whether these mechanisms are associated with the occurrence of PLEs in people with narcissistic grandiosity. Therefore, in the present study, we approached a network analysis in order to investigate pathways from narcissistic grandiosity to PLEs taking into consideration the mediating effect of common psychological mechanisms. The study was based on a non-clinical sample of 1647 individuals, aged 18-35 years. Data were collected through self-reports administered in the online survey. There were no direct connections between narcissistic grandiosity and PLEs. However, four pathways connecting narcissistic grandiosity and PLEs through the effect of one mediating psychological mechanism were identified. These mechanisms covered external attribution biases, the need to control thoughts, social cognition, and emotion regulation through fantasizing. Among them, the shortest pathway led through the effects of external attribution biases. Age, gender, education and lifetime history of psychiatric treatment were included as covariates in a network analysis. Findings from this study indicate that higher levels of external attributions, the need to control thoughts, impairments of social cognition, and emotion regulation strategies based on fantasizing might be associated with the development of PLEs in people showing narcissistic grandiosity. These observations indicate potential targets for therapeutic approaches that aim to reduce the risk of developing comorbid psychopathology in people with grandiose narcissism traits.

Circadian Blood Pressure Profile in Pediatric Patients with Primary Hypertension.

Our study aimed to evaluate factors affecting circadian BP profile and its association with hypertension-mediated organ damage (HMOD) in pediatric patients with primary hypertension (PH). The study included 112 children (14.7 ± 2.1 age, 79 boys, 33 girls) with untreated PH. Non-dipping was defined as a nocturnal drop in systolic or diastolic BP (SBP, DBP) < 10%, and a nocturnal drop >20% was defined as extreme dipping. The nocturnal SBP drop was 10.9 ± 5.9 (%), and the DBP drop was 16.2 ± 8.5 (%). Non-dipping was found in 50 (44.6%) children and extreme dipping in 29 (25.9%) patients. The nocturnal SBP decrease correlated with BMI Z-score (r = −0.242, p = 0.010) and left ventricular mass index (LVMI) (r = −0.395, p = 0.006); diastolic DBP decrease correlated with augmentation index (AIx75HR) (r = 0.367, p = 0.003). Patients with a disturbed blood pressure profile had the highest LVMI (p = 0.049), while extreme dippers had the highest augmentation index (AIx75HR) (p = 0.027). Elevated systolic and diastolic BP dipping were risk factors for positive AIx75HR (OR 1.122 95CI (1.009−1.249) and OR 1.095 95CI (1.017−1.177). We concluded that disturbed circadian BP profile was common in children with PH and should not be considered a marker of secondary hypertension. A disturbed circadian BP profile may be associated with higher body weight. In pediatric patients with PH, non-dipping is associated with increased left ventricular mass, and extreme dipping may be a risk factor for increased arterial stiffness.

Evaluation of Active Renin Concentration in A Cohort of Adolescents with Primary Hypertension.

Our study aimed to assess active renin concentration in children with primary hypertension. Thus, we evaluated active renin concentration, clinical parameters, office and ambulatory blood pressure, and biochemical parameters in 51 untreated adolescents with primary hypertension (median: 14.4 [interquartile range-IQR: 13.8-16.8] years) and 45 healthy adolescents. Active renin concentration did not differ between patients with hypertension and healthy children (median: 28.5 [IQR: 21.9-45.2] vs. 24.9 [IQR: 16.8-34.3] [pg/mL], p = 0.055). In the whole group of 96 children, active renin concentration correlated positively with serum potassium and office and ambulatory systolic and diastolic blood pressures. Among children with hypertension, patients with isolated systolic hypertension had lower renin concentration than patients with systolic-diastolic hypertension (26.2 [IQR: 18.6-34.2] vs. 37.8 [IQR: 27.0-49.6] [pg/mL], p = 0.014). The active renin concentration did not differ between patients with isolated systolic hypertension and healthy children. In multivariate analysis, diastolic blood pressure Z-score (beta = 0.238, 95 confidence interval [0.018-0.458], p = 0.035) was the only predictor of active renin concentration in the studied children. We concluded that active renin concentration is positively associated with blood pressure and potassium in children, and diastolic blood pressure was the strongest predictor of renin level. Patients with isolated systolic hypertension may differ from patients with systolic-diastolic hypertension in less severe activation of the renin-angiotensin-aldosterone system.

24-hour central blood pressure and immune system activation in adolescents with primary hypertension - a preliminary study.

Introduction: Adult and pediatric data suggest a positive relationship between the extent of subclinical inflammation, blood pressure, and hypertension-mediated organ damage (HMOD) in primary hypertension (PH). 24-hour (24-h) ambulatory blood pressure (ABPM) and central blood pressure (CBP) are strong predictors of HMOD. Our study aimed to analyze the relationship between 24-h central ABPM, subclinical inflammation, and clinical data in adolescents with PH. Material and methods: In 28 untreated adolescents with PH (14.50 ±2.27 years) and 25 healthy peers (14.76 ±2.83 years), we analyzed 24-h peripheral and central ABPM, markers of subclinical inflammation (neutrophil-to-lymphocyte ratio - NLR, platelet-to-lymphocyte ratio - PLR, mean platelet volume - MPV), and clinical and biochemical data. Results: Patients with PH had higher 24-h peripheral and central blood pressure than healthy peers. In all 53 patients, we found significant (p < 0.05) positive correlations between NLR, PLR and 24-h central systolic, diastolic, and mean blood pressure (24-h cSBP, 24-h cDBP, 24-h cMAP), between 24-h central augmentation index corrected for heart rate 75 (24-h cAIx75HR) and platelet count. In 28 patients with PH, 24-h cAIx75HR correlated with low-density lipoprotein (LDL) cholesterol (R = 0.442), and ambulatory arterial stiffness index with body mass index (BMI) (R = 0.487), uric acid (R = 0.430), and high-density lipoprotein (HDL) cholesterol (R = -0.428). Conclusions: Increased central 24-h blood pressure may be associated with immune system activation in adolescents with primary hypertension. In adolescents with primary hypertension, dyslipidemia and hyperuricemia are risk factors for increased arterial stiffness. Further studies on central and peripheral blood pressure in terms of their relationship with inflammation in these patients are needed.

Early Vascular Aging in Children With Tuberous Sclerosis Complex.

Objectives: Experimental data indicate that activating mutations in the mTOR (mammalian target of rapamycin) pathway may lead to abnormal arterial wall structure. Vascular anomalies like arterial stenoses are reported in pediatric patients with tuberous sclerosis complex (TSC). In addition, large renal lesions (angiomyolipoma-AML and cysts) are risk factors for arterial hypertension in adult patients with TSC. This study aimed to assess blood pressure, including central blood pressure and arterial damage (early vascular aging-EVA) in children with TSC. Materials and Methods: In a group of 33 pediatric patients with TSC (11.13 ± 4.03 years, 15 boys, 18 girls), we evaluated peripheral and central office blood pressure, 24-h ambulatory blood pressure, and arterial damage: aortic pulse wave velocity (aPWV) [m/s], [Z-score], augmentation index (AIx75HR [%]), common carotid artery intima-media thickness (cIMT) [mm], [Z-score], stiffness of common carotid artery (E-tracking), renal lesions in magnetic resonance and ultrasonography, and selected biochemical parameters. The control group consisted of 33 healthy children (11.23 ± 3.28 years, 15 boys, 18 girls). Results: In TSC group 7 (21.2%) children had arterial hypertension, 27 (81.8%) children had renal angiomyolipomas, 26 (78.8%)-renal cysts, and 4 (12.1%) patients were treated with mTOR inhibitors (2 patients with everolimus and 2 patients with sirolimus) at the moment of evaluation. Children with TSC had higher central systolic blood pressure (AoSBP) (98.63 ± 9.65 vs. 90.45 ± 6.87 [mm Hg], p < 0.001), cIMT (0.42 ± 0.05 vs. 0.39 ± 0.03 [mm], p = 0.011), cIMT Z-score (0.81 ± 1.21 vs. 0.16 ± 0.57, p = 0.007), aPWV (4.78 ± 0.81 vs. 4.25 ± 0.56 [m/s], p = 0.003) and aPWV Z-score (-0.14 ± 1.15 vs. -0.96 ± 0.87, p = 0.002) compared to healthy children, without differences in AIx75HR (8.71 ± 15.90 vs. 5.24 ± 11.12 [%], p = 0.319) and stiffness of common carotid artery. In children with TSC AoSBP correlated positively with serum cystatin C concentration (r = 0.377, p = 0.030) and with maximum diameter of renal cyst (R = 0.419, p = 0.033); mean arterial pressure (MAP) 24 h Z-score correlated with serum cystatin C concentration (R = 0.433, p = 0.013); and aPWV Z-score with daily urinary albumin loss [mg/24 h] (R = 0.412, p = 0.029). Conclusions: Children with tuberous sclerosis complex are at risk of elevated central blood pressure and early vascular aging. In children with TSC, blood pressure and arterial stiffness are related to renal involvement.

Arterial stiffness in children with primary hypertension is related to subclinical inflammation.

INTRODUCTION: The immune system can trigger an inflammatory process leading to blood pressure elevation and arterial damage. The aim of the study was to assess the relation between subclinical inflammation and arterial damage in pediatric patients with primary hypertension (PH) and to establish the usefulness of neutrophil-to-lymphocyte (NLR) and platelet-to-lymphocyte (PLR) ratios, and mean platelet volume (MPV) as markers of arterial damage in these subjects. MATERIAL AND METHODS: In 119 children with PH (14.94 ±2.76 years) and 45 healthy children (14.91 ±2.69 years) we analyzed markers of subclinical inflammation (NLR, PLR, MPV), clinical and biochemical parameters, office blood pressure, ambulatory blood pressure monitoring (ABPM), central blood pressure, aortic pulse wave velocity (aPWV), augmentation index corrected for heart rates 75 (AIx75HR), carotid intima media thickness (cIMT), and common carotid artery stiffness (E-tracking). RESULTS: Children with PH were characterized by significantly higher neutrophil (3.9 ±1.7 vs. 3.0 ±1.0 [1000/µl], p < 0.001) and platelet counts (271.9 ±62.3 vs. 250.3 ±60.3 [1000/µl], p = 0.047), NLR (1.9 ±1.5 vs. 1.3 ±0.4, p = 0.010), PLR (131.4 ±41.9 vs. 114.7 ±37.6, p = 0.020), aPWV (5.36 ±0.88 vs. 4.88 ±0.92 m/s, p = 0.004), and cIMT (0.46 ±0.07 vs. 0.43 ±0.07 mm, p = 0.002) compared to healthy children. In PH children NLR correlated positively (p < 0.05) with: systolic, diastolic and mean blood pressure in ABPM (r = 0.243, r = 0.216, r = 0.251), aPWV [m/s] (r = 0.241), aPWV Z-score (r = 0.204), and common carotid artery PWVbeta [m/s] (r = 0.202). CONCLUSIONS: There is a link between arterial stiffness and subclinical inflammation in pediatric patients with primary hypertension. Neutrophil-to-lymphocyte ratio may serve as a promising marker of arterial stiffness in pediatric patients affected by primary hypertension.

Serum Sclerostin Is Associated with Peripheral and Central Systolic Blood Pressure in Pediatric Patients with Primary Hypertension.

Recent studies showed the significance of the canonical Wnt/beta-catenin pathway and its inhibitor-sclerostin, in the formation of arterial damage, cardiovascular morbidity, and mortality. The study aimed to assess serum sclerostin concentration and its relationship with blood pressure, arterial damage, and calcium-phosphate metabolism in children and adolescents with primary hypertension (PH). Serum sclerostin concentration (pmol/L) was evaluated in 60 pediatric patients with PH and 20 healthy children. In the study group, we also assessed calcium-phosphate metabolism, office peripheral and central blood pressure, 24 h ambulatory blood pressure, and parameters of arterial damage. Serum sclerostin did not differ significantly between patients with PH and the control group (36.6 ± 10.6 vs. 41.0 ± 11.9 (pmol/L), p = 0.119). In the whole study group, sclerostin concentration correlated positively with height Z-score, phosphate, and alkaline phosphatase, and negatively with age, peripheral systolic and mean blood pressure, and central systolic and mean blood pressure. In multivariate analysis, systolic blood pressure (SBP) and height expressed as Z-scores were the significant determinants of serum sclerostin in the studied children: height Z-score (ß = 0.224, (95%CI, 0.017-0.430)), SBP Z-score (ß = -0.216, (95%CI, -0.417 to -0.016)). In conclusion, our results suggest a significant association between sclerostin and blood pressure in the pediatric population.

Serum Periostin as a Potential Biomarker in Pediatric Patients with Primary Hypertension.

Experimental studies suggest that periostin is involved in tissue repair and remodeling. The study aimed to evaluate serum periostin concentration as potential biomarker in pediatric patients with primary hypertension (PH). We measured serum periostin, blood pressure, arterial damage, biochemical, and clinical data in 50 children with PH and 20 age-matched healthy controls. In univariate analysis, children with PH had significantly lower serum periostin compared to healthy peers (35.42 ± 10.43 vs. 42.16 ± 12.82 [ng/mL], p = 0.038). In the entire group of 70 children serum periostin concentration correlated negatively with peripheral, central, and ambulatory blood pressure, as well as with aortic pulse wave velocity (aPWV). In multivariate analysis, periostin level significantly correlated with age (ß = -0.614, [95% confidence interval (CI), -0.831--0.398]), uric acid (ß = 0.328, [95%CI, 0.124-0.533]), body mass index (BMI) Z-score (ß = -0.293, [95%CI, -0.492--0.095]), high-density lipoprotein (HDL)-cholesterol (ß = 0.235, [95%CI, 0.054-0.416]), and triglycerides (ß = -0.198, [95%CI, -0.394--0.002]). Neither the presence of hypertension nor blood pressure and aPWV influenced periostin level. To conclude, the role of serum periostin as a biomarker of elevated blood pressure and arterial damage in pediatric patients with primary hypertension is yet to be unmasked. Age, body mass index, uric acid, and lipid concentrations are key factors influencing periostin level in pediatric patients.

[Uric acid in children and adolescents with primary hypertension]. / Kwas moczowy u dzieci i mlodziezy z nadcisnieniem tetniczym pierwotnym.

Increased concentration of uric acid may play a role in the pathogenesis of primary hypertension (PH). AIM: The aim of the study was to assess concentration of uric acid and to assess its correlation with selected clinical and biochemical parameters in children with PH. MATERIALS AND METHODS: In a group of 57 untreated pharmacologically children with PH (44 boys, 13 girls, mean age 14.99±2.84 years) following parameters were assessed: serum uric acid concentration, blood pressure in office measurement and in 24-hour ambulatory blood pressure monitoring (ABPM), and selected clinical and biochemical parameters. Control group consisted of 20 healthy children (mean 14.11±2.99 years). RESULTS: Serum uric acid concentration was significantly higher in children with PH compared to healthy children (5.72±1.38 vs. 4.55±1.07 mg/dL; p=0.001). In patients with PH, its concentration was significantly higher in boys compared to girls ((6.12±1.20 mg/dL vs. 4.35±1.13 mg/dL, p<0.001), no such difference was found in healthy children. In the PH group, uric acid concentration correlated positively with age (r=0.426, p=0.001), height (r=0.557, p<0.001), weight (r=0.518, p<0.001), weight Z- score (r=0.296, p=0.025), BMI (r=0.316, p=0.017), neutrophil count (r=0.280, p=0.035), systolic blood pressure (r=0.375, p=0.004) and pulse pressure (r=0.444, p=0.001) in ABPM and negatively with HDL cholesterol, heart rate (r=-0.310, p=0.02 (1=-0.309, p=0.020) and nighttime diastolic blood pressure dip (r=-0.268, p=0.044) in ABPM. In multivariate analysis, the determinants of uric acid concentration in children with PH were sex (Β = 0,367, 95%CI(0.122-0.611), p=0.004) and weight Z-score (Β= 0.254, 95%CI(0.005-0.504), p=0.046). CONCLUSIONS: Children with PH have increased serum uric acid concentration compared to healthy children. The risk factors for hyperuricemia in pediatric patients with PH are male sex and high body weight.

Circulating calcification inhibitors are associated with arterial damage in pediatric patients with primary hypertension.

BACKGROUND: Circulating calcification inhibitors: fetuin A (FA) and osteoprotegerin (OPG) together with soluble ligand of receptor activator of nuclear factor kappa-B (sRANKL) have been linked to vascular calcifications and arterial damage. This study aimed to evaluate relationships between FA, OPG, sRANKL, and arterial damage in children with primary hypertension (PH). METHODS: In this cross-sectional single-center study, calcification inhibitors (FA, OPG, sRANKL) levels were measured in blood samples of 60 children with PH (median age 15.8, IQR: [14.5-16.8] years) and 20 age-matched healthy volunteers. In each participant, peripheral and central blood pressure evaluation (BP) and ambulatory BP monitoring (ABPM) were performed. Arterial damage was measured using common carotid artery intima media thickness (cIMT), pulse wave velocity (PWV), augmentation index (AIx75HR), and local arterial stiffness (ECHO-tracking-ET) analysis. RESULTS: Children with PH had significantly higher peripheral and central BP, BP in ABPM, thicker cIMT, higher PWV, and AIx75HR. FA was significantly lower in patients with PH compared to healthy peers without differences in OPG, sRANKL, and OPG/sRANKL and OPG/FA ratios. In children with PH, FA level correlated negatively with cIMT Z-score and ET AIx; sRANKL level correlated negatively with ABPM systolic blood pressure (SBP), SBP load, diastolic BP load, and AIx75HR; OPG/sRANKL ratio correlated positively with SBP load, while OPG/FA ratio correlated positively with ET AIx. In multivariate analysis, FA was a significant determinant of cIMT (mm) and cIMT Z-score. CONCLUSIONS: This study reveals that in children with primary hypertension, arterial damage is related to lower fetuin A concentrations.

Markers of endothelial injury and subclinical inflammation in children and adolescents with primary hypertension.

INTRODUCTION: Adhesion molecules: E-selectin and intercellular adhesion molecule 1 (ICAM-1) are well-established markers of endothelial injury. The aim of the study was to assess the relation between E-selectin and ICAM-1 and clinical and biochemical parameters in children and adolescents with primary hypertension (PH). MATERIAL AND METHODS: In 77 patients with PH (15.04 ±2.62 years, 50 boys, 27 girls) we evaluated serum E-selectin, ICAM-1, and selected clinical and biochemical parameters including inflammatory indicators and ambulatory blood pressure monitoring (ABPM). RESULTS: The E-selectin concentration was 55.63 ±26.49 ng/ml and the ICAM-1 concentration was 302.17 ±67.14 ng/ml. E-selectin and ICAM-1 correlated (p < 0.05) with BMI Z-score (r = 0.24, r = 0.29), ICAM-1 also with uric acid (r = 0.35), HDL-cholesterol (r = -0.28), platelet-to-lymphocyte ratio (r = 0.26), and systolic and mean blood pressure variability (r = 0.24, r = 0.24); in boys ICAM-1 correlated with mean platelet volume (r = 0.29). In multivariate analysis the only significant predictor of E-selectin was mean arterial pressure during 24 hours (ß = 0.329, 95% CI: 0.012-0.646) and of ICAM-1 - uric acid (ß = 0.430, 95% CI: 0.040-0.819). In 27 children with newly diagnosed PH E-selectin correlated negatively with diastolic blood pressure dipping (r = -0.54, p = 0.004) and positively with ambulatory arterial stiffness index (r = 0.51, p = 0.012). CONCLUSIONS: Elevated mean arterial pressure and hyperuricemia are risk factors of endothelial damage in paediatric patients with primary hypertension. In children with untreated primary hypertension there may be a relation between endothelial damage and disturbed circadian blood pressure profile.

[Pulmonary embolism in a girl with nephrotic syndrome and factor V Leiden - case report]. / Zatorowosc plucna u dziewczynki z zespolem nerczycowym i czynnikiem V Leiden ­ opis przypadku.

Thromboembolic complications are found in 2-3% of children with nephrotic syndrome (NS); this increased risk is caused by hypovolemia, hemoconcentration, increased number and activity of platelets, hyperfibrinogenemia and loss of coagulation inhibitors. Risk is even higher in case of additional factors e.g. congenital thrombophilia. CASE REPORT: Girl with NS aged 17 11/12 years was admitted to hospital due to respiratory tract infection with cough and back pain. NS started 9 months earlier and she had two bouts of disease, and was treated only with prednisone (current dose - 60 mg/48h). On admission she was without any abnormalities on auscultation, with BP 111/65 mmHg, HR 80 bpm, satO2 99%. Lab results showed the increase of WBC 18.3×103/µL, D-dimers 23038 µg/L and proteinuria 900 mg/dL. Other values of examined parameters were in normal limits. Chest X-ray and ECG were also normal. Presumptive diagnosis of pulmonary embolism was made and the patient was given 1000IU of antithrombin III and nadroparine (2x90IU/kg/24h s.c.). In ECHO the occlusion of left pulmonary artery and preserved blood flow in right were revealed. In angioCT clot nearly filling lumen of left pulmonary artery, clot in intermediate part of right pulmonary artery, and focus of pulmonary infarction in 10th segment of left lung were found. Doppler USG of lower limb veins did not reveal thrombi or perforator vein incompetence. Treatment with nadroparine was continued, and rapid improvement of clinical condition and disappearance of pain and cough were observed. Mycophenolate mofetil was added, which resulted in subsidence of proteinuria. Rivaroxaban was used in prophylaxis of recurrences of thromboembolism. Tests for thrombophilia revealed factor V Leiden in patient.

[Two-stage revision procedure for septic complicated endoprosthesis of the hip]. / Dwuetapowa replantacja stawu biodrowego w leczeniu powiklan zapalnych endoplastyki.

Total hip arthroplasty is commonly used way for treatment of degenerative changes of a hip joint. Continuous progress of medicine enables use of more and more modern implants, that are supposed to provide to patients comfortable and painless motility. Nevertheless, with increasing number of implanted endoprostheses, rising numer of loosened impants is observed. Proper laboratory dignostics and postoperative proceedings as well as systematic follow up with standard X-ray scans allow for early recognition of loosened prostheses and implementation of surgical procedure. In the article two-stage method for treatment of septic loosened primary total hip arthroplasties applied in CMKP Orthopedic Clinic in Otwock, Poland as well as results of treatment of selected cases are presented.

[Conduct and tactics of infections after hip arthroplasty]. / Taktyka postepowania w zakazeniach stawu biodrowego po endoplastykach.

The number of arthroplasty surgeries is growing globally, bringing about an increase in the absolute number of infected complications. No precise statistics of complications are available in Poland. The present paper discusses the main causes of infected complications of hip arthroplasty. The object is to present both pre-surgery prophylaxis and the treatment of an infected complication adjacent to the endoprosthesis. Infections are commonly divided after Coventry and Fitzgerald. The most common pathogens in infected endoprostheses include Staphylococcus aureus and Staphylococcus epidermidis, while the treatment of infections with the Gram-negative flora poses many problems. Discussed within treatment of infected complications of hip arthroplasty has been one- and two-stage surgical treatment with temporary implants--"spacers"--combines with prolonged antibiotic therapy. Important within the post-surgery treatment is prolonged monitoring of the infective agents (CRP and SR).
